.'BUNDLING PRESS.

Application filed October 31, 1925, Serial No. 65,994, and in Germany ctober 21, 1924.

rlhis invention relates .to a. device for pressing bundles ot paper, textiles and the like, and of the kind in which the bundle is compressed between two sets of plates one oit which is carried by plungers connected to al reciprocating frame.

According to the present invention the pressure `frame is controlled by an endless chain which is guided over rollers and actuated by the 'foot lever through the medium ci' a pawl and ratchet mechanism, the pawls being spring-controlled and provided with arms which fro-operate with the hand lever for throwing the pawls into and out oiQ gear.

The hand lever is also connected to a mechanism whereby the initial lowering of the pressure frame is readily and quickly eliected simultaneously with the operation oit the pawls.

F ig. 1 of the accompanying drawings represents a side view of the machine,

Fig. 2, a horizontal section ol' the saine,

Fig. 3, a view of the hand lever with attached mechanism, and

Fig. 4, a plan ot' the latter.

The machine is composed of a :trame 1 which carries a top plate 2. A set o' spaced brackets 3 is mounted on the top 2 and formed with supporting plates 8 for the reception ci' the bundles to be compressed. Another set of plates 5 is held above the plates 3 by plungers 4 which are guided Vin the brackets 3 and secured to a trame 6 whereby the plates 5 can be actuated for compressing the bundles against the plates 3. As `the plates are spaced from each other and raised from the top 2, the bundles can easily be tied up in their compressed state.

For controlling the frame 6, an endless chain 7 is provided which is secured to the trame and guided over a sprocket wheel 9 and over deflection pulleys 10. A weight 11 is connected to the chain as a counterbalance tor the trame and the plungors, the weight being heavy enough to maintain the structure in its highest position. rlhe sprocket wheel 9 is secured to a ratchet wheel 12, both being rotatably arranged on a sha-ft 8 which is carried by brackets 13 supported on a cross-bar 14 in the machine iframe. On the same shaft, a U-shaped shackle 16 is arranged so that it can rock independently of the. wheels. A shaft 18, held by the shackle 16, engages with its ends in slots 19 made in another shackle 2() which is arrangedto rock about a shaft 21, the latter being carried by the brackets 18. rlhe shackles 16 and 18 can'be rocked by means ot a treadle 22 having at its free. end a toot plate 23. A pawl 17 adapted tor engagement with the ratchet .wheel 12, is secured to the shaft 18 which also carries, outside the shackle 16, an arm 29. A spring 44 acts on the arm 29 and. tends to hold the pawl in engagement with the ratchet wheel. This is normally prevented by a lever arm v27 which for this purpose rests on the cranked` end of the arm 29. The lever 27 is arranged to rock about the shaft 21 and controls a shackle 26 which normally supports an arm connected to a detent pawl 24. A spring 45 tends to hold the pawl 24 in engagement with the ratchet wheel 12, such engagement being normally prevented by the shackle 26. A spring 4G maintains the treadle 22 normally in raised position.

A rod 28 connects the lever 27 with a Jell-crank 30 who-se opposite end is pivoted to a. slotted plate 32. A hand-operated lever 33, which rocks about a pivot 47, carries a bolt 49 which engages the slot of the plate 32. lt also carries a stud which, in the lowest position of the lever, strikes against an inclined surface 31 o-n the plate 32 so as to depress the latter and operate the bellcrank 30. When the bellcrank is thus operated, the rod 28 is raised and the lever' 27 turned for releasing the two pawls which then enter into engagement with the ratchet wheel 12. rlhe lever 33 carries a roller 34 which bears against a curved arm ranged on a shaft '48 and connected by means ot a sleeve 51 with another curved arm 41. The latter arm engages a roller 42 carried by the frame 6.

The lever 33 is arranged at one side of the machine frame. The levers 40 and 41 and the sleeve 51 transmit the motion to the more centrally disposed roller 42, and the lever 40, moreover, serves to secure greater leverage on the plungers.

After the bundle has been adjusted bctween the presser plates 3 and'. the` lever 33 is depressed so as to 'rock the arms 40 and 41. Acting` on the roller 42, the arm 4l forces the plates 5 down against the bundle. As the stu-d 35 engages the plate 32 and operates thebell-crank a0. the pawls 17 and 24 are released so 'that the compression of the bundle can .now be effected through the me diuni ot the ratchet mechanism which tor v ried'. by the lever portion 33.

this purpose is operated by means of the Vtreadle. After the bundle has been tied, the

lever 33 is operated for disengaging the pawl from the ratchet wheel l2. For this purpose the bolt e9 engages the plate 32 at the upper end of its slot, the rod 23 being thereby depressed and thev lever 27 forcibly applied. to the arms 29 and 25 oi' the pawls. As the wheels l2 and 9 can then turn freely, the plungers will' be raised by the weight ll. The upward movement or'l the plungersis limited by the arms controlled by the, lever l33 for which latter an abutment- 433 is provided. Tov allow the bolt i9 to be raised slightly beyond the position deterniinedY by the abutment 43, if it should be required for disengaging the pawls ronr the` ratchet wheels, the lever 33 is jointedso that it can bend about the shaft which'` carriesfthc roller 3i'. The outerportion of the lever is doublearmed and engages the. inner portion by means. of a lug 50 so as to be rigidly supported by the inner portion for downward movement; `The inner end of thel outer' portion is pointed 'for engagementV Vwith a V- shaped notchu made'ina slide36. Vllhis slide has a slot 37 whereby it is guided ona block 43 connected to the inner portion 33 of the lever, and it is'pressedtorwardby a lever 39 which is controlled byV a strong spring 3S. Thelever 39 andthe spring, 33 are both car- `When lifting Vforce is applied to the tree end of the lever 33 after the portion 33 has come to rest against the abutment 43, the slide 36 yields so as to allow the lever to bend about the pivot 34. Under the action of the spring 38 and the bevelled abutting snr-faces of the slide and the lever, they parts of the latter willi berestored to. their normal relative position assoon as the part 33 is releasedi I claiinz-f 1.
